I enjoy using astronomy software to explore the universe, and lately I’ve concentrated on some of the planets in our solar system. I’ve already covered Jupiter and Saturn, so this post covers another gas giant in our solar system. Neptune is the 8th (and last) planet in our solar system. Neptune is the 4th largest planet (in diameter) and is around 30 times further out from the sun than Earth.

Neptune was discovered in 1846. It has a predominately hydrogen and helium atmosphere, with traces of methane that help give it a blue hue. Voyager 2 flew by it and took loads of pictures back in 1989.

This is a screen shot taken with Starry Night Pro 6 today:

There is a lot of data about Neptune in Starry Night, or you can select Starry Night’s “Info” tab and select “” beside the “Extended Info” field to get data on Neptune from Wikipedia.

This is a screen shot of Triton (taken with Starry Night today), the largest of the 11 moons of Neptune:

Here is a picture of Neptune as it would be seen looking west on Triton – perhaps from the window of a visiting spacecraft:

This is an excellent screen shot of Neptune taken with the Red Shift 7 astronomy software:

This is a screen shot of an image of Neptune (magnified to 400%) retrieved with Mathematica 8:

There is more data available on Neptune using AstronomicalData (introduced in Mathematica 7), which returns properties on planets, moons, stars and galaxies. Check it out at the Wolfram website.

This is an image of Neptune from NASA‘s website:

There are many sources for astronomers – amateur and professional – besides telescopes. In this age of the internet, we has so much data available that formerly was only found in libraries. Take some time away from television and video games and explore the wonders of the sky. You have the ability and resources, you just need the motivation to see that space is more than Star Wars and Aliens.

Introduction to an on-going review

Wolfram released version 8 of Mathematica on November 15, 2010, and it is similar to the version 6 update where there are many enhancements and improvements over the previous version. This review will be ongoing – I will revise and add to it as I become more familiar with the product and so I encourage readers to periodically check back to see updates to the material.

BREAKING NEWS (4-27-2011)

Wolfram released an update to Mathematica 8, version 8.0.1 is now available. Click here to see our post on the new version of Mathematica.

BREAKING NEWS (3-8-2011)

I was informed by Wolfram’s PR firm on 12/01/2010 that the Player plug-in for interaction with Wolfram Demonstrations will not be available before January, 2011, and the plug-in would support the latest versions of all major browsers on Mac/Windows, including Firefox, Safari, Chrome, and Opera on both platforms, and IE for Windows. Under Macintosh, the plug-in requires that you run the installer in the disk image–i.e., copying is insufficient to set it up.

As of today (3/8/2011) Mathematica Player and Player Pro have been replaced by the CDF (Computable Document Format) Player, which is available for download from Wolfram. The Mac OS X version includes plug-ins for Safari, Firefox, Chrome, and Opera. The Windows 7/Vista/XP version supports the same browsers as the Mac OS X version, but includes support for IE. The Linux version currently is a desktop application – browser plug-ins are currently under development.

Click here if you want to test whether you already have the CDF Player installed.

Mathematica users that want to publish MM6 and 7 Notebooks for Player can still do so, using Wolfram’s online service.

RELEASE DATES FOR FOREIGN LANGUAGE VERSIONS OF MATHEMATICA 8 (Updated 3/30/2011): Per Wolfram’s PR, Mathematica 8 Japanese Edition was available on 1/20/2011, and Mathematica 8 Chinese Edition was available 3/23/2011. Mathematica 8 Spanish Language Kit will be available in early 2011 (Unlike fully localized editions, this plug-in kit localizes the interface (menu, palettes, error messages) but not the documentation)-still no release date as of 1/20/2011.

Getting Started

I downloaded the 1 GB file from Wolfram and installed it on my 2.26 GHz dual core Macbook laptop, where it took up nearly 2.9GB for the installation.

Tip! If you have an older version of Mathematica already installed, rename the executable by appending the version to the file name, so that older version is not overwritten during installation of version 8. NOTE: Wolfram’s PR firm confirmed this was intentional in an email to me I received on 12/1/2010.

The initial version 8 screen is shown here:

The Welcome screen is new – better organized than earlier versions.

First, the new browser plug-in

One of the first things I wanted to check was the new browser plug in which comes with the software. Be aware that the new Mathematica 8 Player was not available when this product shipped in mid-November, so people strictly using the player will need to wait to test this added functionality.

This was seen while using a Safari plug in – Mathematica launched Safari even though I already had Firefox running. I now have the list of browsers that will have this plug in (see Very Important Notes below). I suspect user demand will drive the plug in release for other browsers.


Busy day yesterday, but I received more information from Wolfram’s PR about the browser plug-in that I want to share with you. Per the PR contact:

“The browser supports notebook content in two modes.  The first mode is a full-screen mode, which you can easily see right now by going to any web page which hosts a notebook file.  For example, go to and, for any demonstration, click “Download Live Version.”  This will work for any notebook linked on any website (so long as the web server isn’t configured to override the MIME type, at least).

The second mode is an embedded mode.  For example, you could embed a Mathematica Manipulate output in a regular web page.  Right now, we only have one public example of that, which is shown as part of the installation here:

I tested the first mode this morning by going to Wolfram’s Demonstration Project page and went to the Physical Sciences/Earth Sciences/ Meteorology page and checked out the Sea Level demonstration (contributed by Herbert W. Franke):

I selected DOWNLOAD LIVE VERSION and saw this in my browser as the plug-in loaded:

The first time I used the plug-in in Firefox (ver 3.6.12) I had to reload the page to see and use the demonstration. The demo was accessible within my web browser and I could manipulate the controls just like working within Mathematica.

Next (because I’m currently working on a Genetic Programming project) I checked out the Order of Operations Tree demonstration (contributed by Sarah Lichtblau) and was able to change the formulas to use for the tree:

Finally I went to the Physical Sciences/Astronomy page and selected the Bump Map of Mars (contributed by Yu-Sung Chang) and selected DOWNLOAD LIVE VERSION and was able to manipulate the controls from the browser:

I rotated the planet and saw Olympus Mons (as well as the three smaller shield volcanoes that make up the Tharsis Montes region below it). Nice detail in the demonstration – not as much detail as I’d prefer, but still usable to show geological features of the red planet.

NOTE: Two times when I tried to open demonstrations (including Bump Map on Mars) they did not display properly: there was a gray box in place of the demonstration. Both times I reloaded the browser page and it fixed the issue each time. I am using Firefox 3.6.12 on a Mac running OS X 10.6.5 and did not test on another browser or operating system, so I informed Wolfram’s support about the issue – they were unable to reproduce the problem.

Moving on beyond the browser plug-in

Time to get back to our review of new Mathematica features. I started the software and did a spot check to verify previous functionality. I periodically use Mathematica to gather astronomical data and so I tested the AstronomicalData function. I produced a table with the 8 planets names and images:

This function provides extrasolar system data as well as planetary information and is my favorite function from version 7 – still works fine. The version 8 documentation says that this function was improved in this release – an email from Wolfram’s PR firm explained that this function was only enhanced in the ability to access data from Wolfram|Alpha.

OK,  lets take a look at the new features in Mathematica 8.

New Features

1. Free-form linguistic input/Integration with Wolfram|Alpha

Free-form linguistic input is a fancy way of saying that you enter content using plain English and still get results. Nice. When I saw this feature during the demo for this release, I understood the rationale. Wolfram is helping new users start using their software before they need to learn all of the aspects of the software’s programming syntax.

I opened a new notebook and entered “= radius neptune/earth” to test this functionality – I just wanted a comparison of the size of Neptune versus Earth. The results I saw are below:

I like this, because it provides both the solution to the query plus the equivalent Mathematica syntax. This test also demonstrates the Integration with Wolfram|Alpha functionality as it retrieved the data from Alpha.

Wolfram’s decision to add the ability to retrieve data from Wolfram|Alpha right into notebooks is appreciated. For some excellent examples of notebooks from Wolfram, check out this link.

A Quick Overview of Wolfram|Alpha

My previous post shows the integration of Mathematica with Wolfram|Alpha, Wolfram’s computational knowledge engine. Since I never reviewed that new service I want to mention it now. I went to their website and did a few searches. I first search was requesting data on extra solar planets this is what I saw:

It took a lot of scrolling to go down through the list of data returned by this search, and I saved the data as a PDF for future reference. I believe this was always available since Wolfram|Alpha was made available, but this was the first time I used it and I like what I see.

My next search was to see if real data agrees with the pseudo-experts that deny global warming and this was the result:

After looking at the graph, even thought I’m no expert I’d have to say it appears that the temperature on our planet is increasing after all.

I like having internet access to scientific and technical data without needing to be concerned about the validity of that data. I would reference Wolfram|Alpha if citing from it, but I would never use data from Wikipedia in a paper. On back to the review of new features in the software.

2. New algorithms for real time image capturing

During the demo, Jon showed how easy he could configure Mathematica to act like a security system by enabling his web cam and utilizing the ability of Mathematica to only send updated images when he moved. This is important for people doing image analysis for security identification systems as well as pattern recognition.

For one test I used the built-in camera of my Macbook (although you can specify a different camera for input) to capture a picture of my alma mater t-shirt using ImageCapture to produced a picture in the notebook. This was the Mathematica screen:

I could save the image in my notebook to a free-standing file in a number of different formats including JPEG, JPEG2000, GIF, etc. Not a major feature but still useful.

Mathematica can capture a single image or record a series of images. Consider how companies could take advantage of this feature. A company using 12 web cams to cover their warehouses need to handle the constant bandwidth of 12 signals, which also requires one or more people to stare at the screens looking for movement, If the only time a camera sends a signal is when something moves, no signals are transmitted so no transmission bandwidth is needed and this changes a dedicated task to a side job for an employee. This is my favorite enhancement so far during my evaluation of this software.

3. New Import and Export Formats

The 26 new import/export formats are:

There are a lot of new import/export formats to test, so I’ll test the C and ICS import/export functionality to save time for assessing other improvements. Why? I already expressed an interest in exporting C, and I have my old Palm Pilot LifeDrive with years of data that I want to move to a more modern (and supported) hardware platform.

4. Automatically convert Mathematica programs into C code

I like writing C and now Wolfram lets you take a Mathematica program and directly convert it into C code for free-standing or integrated use. Nice. No, very nice! During the demonstration I asked about converting programs into object-oriented code (C++/C#/Java) and was told that decision was market-based. Wolfram does sell a C++ solution called MathCode C++ which is compatible with Mathematica 7, but not (as of 1/20/2011) listed as compatible with version 8. If enough users request it then it could happen in a future release. Wolfram didn’t promise this would happen, but they do listen to customer suggestions so let them know if you too would like to see support for object-oriented code generation.

Important Note (3/7/2011)

I spoke with Wolfram’s PR dept on 1/20/2011 and they said that the MathCode C++ is on the list for updating to Mathematica version 8 compatibility, but they do not have a date when we can expect that update. They did say they don’t have any known issues with MathCode C++ and Mathematica version 8. If anyone reads this post and has seen problems with this combination, please let us (and Wolfram) know.

I also requested a list of add-ons being updated for version 8 – the coordinator said all add-ons are being tested for compatibility with Mathematica 8, but there is no date when that testing will be finished.

MathCode C++ is still listed as Mathematica 7 Compatible as of 3/7/2011.

5. Dynamic Library Loading

Incorporate external C and C++ libraries, which is nice for developers integrating Mathematica with other lab systems. Mathematica can share data with external libraries using LibraryLink functions to pass integers, reals, arrays, strings, Mathematica expressions, as well as pass messages.  Sweet.

6. Enhanced 2D and 3D Graphics and Drawing Tools

The primary area where Mathematica 7 stood out over version 6 was the enhanced graphics capabilities. Version 8 has enhanced scaling and surface texture mapping for 2D and 3D images. In truth, a picture is worth a thousand words and improving the way Mathematica represents data is much needed. I don’t know for sure, but I’d guess this enhancement was based on user feedback, so it does pay to speak up.

Version 8 also has enhanced illustration and drawing tools, which may not beat Photoshop or Illustrator, but they do enhance the quality of work that can be done within Mathematica so this enhancement is a time saver. I do wonder why it took this long to add an easy way to align drawing elements, as that has been a part of most graphic packages for a long time. A new color picker is nice, although I am more inclined to use my browser plug-in or Photoshop for that functionality.

7. UI and Usability

The look-and-feel seems the same between versions 7 and 8, although text processing is improved in version 8. There is a new Custom Style dialog or you can select (and preview) a style using the Format/Style menu options. It is simple to use the supplied styles or create a new one. Something I didn’t see was a way to use external styles from other external word processing products like Word – couldn’t find a menu item or a place on the Classroom Assistant to import styles (but there is a menu option to import stylesheets). If the capability to import or use external styles doesn’t exist yet, it would be one of the enhancements I’d like to see in release 9.


  • Tons of new features and enhancements. I like how the free-form linguistic input will help newcomers learn the correct way to enter Mathematica syntax, and I like the integration with Wolfram|Alpha. I should add that internet access is a necessity if you want access to Wolfram’s dynamic data.
  • Modest hardware requirements – very little needed in the way of processor, system memory, and disk storage space.
  • I love the new Home license, introduced in version 7. One of my previous complaints was the price of this software precluded many home users from buying and using it. The college I attended for undergrad courses did provide current students with a free 1 year licenses for Mathematica and that did influence my decision to go there. I was pleased to learn the school I’m attended for graduate classes also offers a free 1 year license to current students, but eventually I will no longer be attending classes and appreciate being able to afford to buy this useful product when I complete my degree.
  • Improved image capturing and analysis. Capture a single image or a sequence, where sequences can consist of an image that changes over time. The version 7 release was heavily oriented towards working with graphics and I’m pleased to see they continue to improve that aspect of the program.
  • C code generation from Mathematica programs. (Note: I will test this and post my findings during this review-the fact that Wolfram provides this functionality means a lot to me).
  • Integration with external libraries is huge for multiple system environments. A big plus in my eyes.
  • Technical support response is excellent. I contacted them 3 times during my review and they were prompt in responding and helpful.


  • No longer support for OS X running on PPC Macs. This bothers me considering the modest hardware requirements for this upgrade. The problem for most Mac users is that Macs continue to run well even when they are replaced by newer and more powerful computers. I understand other vendors like Adobe made this same business decision, but my 20″ G5 PPC Mac works fine even though it lacks an Intel CPU and now I have to restrict it to version 7 of this software.
  • I also saw that Solaris is no longer in the list of supported operating systems and that is a shame. I didn’t install Mathematica 7 on my Sun workstation but feel others in academia use Suns as well as Linux and would like to see it continue to receive support. I also believe that the Mathematica Player was not supported for Solaris, so perhaps Wolfram felt they did not hear enough from Solaris users when release 7 was released to be a valid reason to drop support for version 8 of Mathematica on Solaris.
  • While it supports creating new styles for text processing, it does not appear to support importing or integrating with external styles. I hope I’m wrong – let me know if I missed that and I’ll correct this review.


Very, very positive so far, and strongly recommended as a new or upgrade purchase. It will take awhile to cover all the improvements and additions in this version of the software, so my final conclusion when come when this review is finished.

I just saw a presentation on version 8 of Mathematica, the newest update to this powerful product used in a wide variety of industries, and I am impressed. There are a ton of enhancements and I will be covering the new release here and for Software Latest. For now, check out the official Wolfram press release:


Wolfram Research Introduces Unique Concept of Linguistically Controlled Computing

New Mathematica 8 Integrates Wolfram|Alpha – One of More Than 500 New Features

November 15, 2010—Wolfram Research today announced the release of Mathematica 8, the latest version of its flagship computation, development, and deployment platform that introduces the breakthrough concept of linguistically controlled computing. Integrating technology of Wolfram|Alpha, the Mathematica-powered computational knowledge engine, makes it possible to enter math or data calculations in plain English and get immediate answers or start an extensive analysis.

“Traditionally, getting computers to perform tasks requires speaking their language or using point-and-click interfaces. One requires learning syntax, the other limits scope of accessible functions,” said Stephen Wolfram, CEO and Founder of Wolfram Research. “Free-form linguistics understands human language and translates it into syntax—a breakthrough in usability. Mathematica 8 is the start of this initiative, but already it is making a real difference to user productivity.”

Free-form input is a new entry point into the Mathematica idea-to-deployment workflow, but Mathematica 8 adds a major new endpoint too: generation of C code and standalone executables. Using Mathematica, organizations no longer have to rely on separate tools for prototyping and deployment, but can complete the entire workflow with one integrated tool.

“It’s amazing that you can start with free-form linguistic input, model or prototype, and end up with a high-performance standalone program or library…all within Mathematica 8’s comprehensive workflow,” said Tom Wickham-Jones, Director of Kernel Technology at Wolfram Research.

Even with these major enhancements at either end of the workflow, the most significant additions in Mathematica 8 are the more than 500 new functions in many new and extended application areas, including:

  • Probability and statistics: largest collection of statistical distributions and automatic high-level solvers including parameter estimation
  • Software development: built-in GPU support, automatic code generation and linking, multicore parallelism, and standalone code deployment.
  • Engineering: integrated control systems and wavelet analysis
  • Graphs and networks: extensive built-in support for the new science of networks
  • Finance: built-in option pricing solvers, financial indicators, and charts
  • Image processing: enhanced image analysis capabilities, such as feature detection

“In all of these domains, you will find dramatic depth of coverage,” stated Roger Germundsson, Director of Research & Development at Wolfram Research. “The functions are designed to work together seamlessly across different domains which allows combining them in new and innovative ways.”

“Rather than build individual spikes of functionality provided by traditional specialist tools, Mathematica‘s concept is based on building up the complete mountain range,” said Conrad Wolfram, Director of Strategic Development at Wolfram Research. “It’s this broad functionality across a wide area that enabled us to build state-of-the-art application areas such as statistics and probability so quickly for Mathematica 8.”


Mathematica 8 is available immediately for Windows XP/Vista/7, Mac OS X, Linux x86, and compatible systems. More product details are available on the Mathematica website:



1. I reformatted the content of the release for this site, but did not modify any of the material.
2. Not all Mathematica products are being updated today. The Home and Student editions will be updated soon – stay tuned here for more information.
3. I am writing an ongoing review of Mathematica, also available on this site, which covers new and interesting existing aspects of this software. Please check back from time-to-time as this will be one of my larger and more in-depth reviews.
